My brother plays games on Windows. I tried to convert him to Linux like two times, but he doesn’t want to do it. He doesn’t even play multiplayer games. Just single-player and co-op games. So Anticheat wouldn’t be a problem. When I said to him that Steam is releasing their own Linux distro, he said: Sure, I will try that.
That was almost 3 years ago and there still isn’t official steamos for desktop.
